A circular mirror is surrounded by a square metal frame. The radius of the
mirror is 4x. The side length of the metal frame is 16x. What is the area of the
metal frame?
Answer: [tex]= 240x^2[/tex]
Step-by-step explanation:
Area of the entire frame = [tex](16x)^2 = 256x^2[/tex]
Area of the mirror = area of a circle = [tex]\pi r^2[/tex]
= [tex]\pi(4x)^2[/tex]
Area of the metal frame surrounding the mirror = square area - circle area
[tex]= (16x)^2-(4x)^2[/tex]
[tex]= 240x^2[/tex]
What is the value of x
Answer:
x = 25
Step-by-step explanation:
The sum of the angles in a triangle are equal to 180 degrees. Since we know the value of one angle is 90 degrees, subtract 90 from 180 to get 90. Now we know the sum of the other two angles must equal 90 degrees. If we add the x and 2x + 15 together, we get 3x + 15 = 90. Subtract 15 from both sides to get 3x = 75. Divide both sides by 3 to get x = 25.

experience. What is the sample size?
answer choices
60
8
15
53
The sample size of the actors is the number of actors Darrien selected
The sample size is 15
How to determine the sample size?From the question, we understand that:
Darrien has 60 actors
This represents the population of the experiment.
Then he selected 15 of the actors, and 8 of them have previous acting experience.
The 15 actors he selected represents the sample of the experiment
Hence, the sample size is 15

The total length that Vulkan jumped on both occasions is 3 1/2 feet.
What are fractions?A fraction is a non integer that is made up of a numerator and a denominator. The numerator is the number above and the denominator is the number below.
How many feet did he jump in all?First convert yard to feet: 1 yard = 3 feet
7/8 x 3 = 21/8 = 2 5/8
Now add the fractions together
2 5/8 + 2 7/8
2 (5 + 7) / 8 = 2 12/8 = 3 1/2 feet

Use technology to convert the polar coordinates (5, 6.1) to rectangular coordinates.
O (0.98, -0.18)
O (0.98, 0.18)
O (4.92, -0.91)
O (4.92, 0.91)
Answer:
(c) (4.92, -0.91)
Step-by-step explanation:
The conversion shown in the attached uses the complex number features of the calculator, so the y-coordinate is shown as an imaginary value. Rounded to 2 decimal places the conversion is ...
(r; θ) ⇔ (x, y)
(5; 6.1) ⇔ (4.92, -0.91)
__
The correct answer choice can be made without the use of technology. The sum of the magnitudes of the values of x and y must not be less than r, eliminating the first two choices. The angle 6.1 radians is near the angle 6.28 radians (2π), so is almost 360°. It will be a 4th-quadrant angle, so its y-component will be negative (eliminating the last choice).
The only viable choice for polar coordinates of radius 5 and angle 6.1 radians is the third choice: (4.92, -0.91).
__
Additional comment
The angle given has no units, so we assume it is given in radians. A calculator can only give a proper answer if it is set to radians mode for angles.

The circumference of the circle is 106.76 km.
What is Circumference of a Circle?Circumference of a circle is defined as the total length of the boundary of the circle.
The concept is same as the perimeter for straight sided figures.
Given that,
The diameter of a circle is 34 kilometers.
Diameter of the circle = 34 kilometers
Radius of the circle = Half of diameter = 34 / 2 = 17 km
Circumference of the circle = 2πr, where r is the radius of the circle.
Circumference = 2π × 17
= 34π
= 106.76 km
Hence the circumference of the circle is 106.76 km.

8. An automobile traveled 320 miles in 6 hours. What is its average speed?
Answer:
The automobile's average speed is 53.33 mph.
Step-by-step explanation:
Since average speed equals total distance traveled divided by the time of the travel we have:
d = 320 mi the distance traveled
t = 6 hr the time of the travel
v = average speed
v = d/t
v = 320/6
v = 53.33 mph
Answer:
about 53 miles per hour
Step-by-step explanation:
320/6 is 53.33 repeated
you divide 320/6 because you need to know how many miles you going in an hour
